OK here's my positive social services story.
I got referred to social services having "missed" some antenatal appointments.
Social services investigated, found the appointment letters had been sent to the wrong address, spoke to me briefly and then closed the case.
However, NHS staff continue to view me as someone with a history of "not engaging" who has had contact with social services because this is what is written in my notes. Add to this low income and "deprived" area and the net result is a VERY high handed and interrogative attitude in every interaction with me.
At the 6 week check I was asked whether I was having difficulty clothing the baby. DS was wearing just a nappy and a (too big) baby-grow because he'd just come from the midwife's room where he was weighed (naked) and the midwife said not to bother dressing him as doctor may want to weigh him herself.
When we came into the health centre he was wearing vest, babygrow, cardigan and hat. The babygrow was large because he was between sizes IYSWIM. I am certain his notes now mention he was inadequately dressed.
Before wrapping up the case, the social worker asked if I had any problems I needed support with. I always think if I'd have said yes, the file would still have been open when the babygrow thing happened, the doctor would have reported it back and that would have been another reason to keep an eye on me.
So while personally I found social services OK, I can see how mistakes can happen. Once the stigma is there it colours peoples perceptions of your parenting, then those perceptions get fed back to social workers and so on...
I had the social worker give me a letter stating there are no child protection concerns. It is my prized possession and I feel VERY lucky to have it.
